//! Opt-in periodic trust report.
//!
//! A digest of what the agent actually did over the reporting window —
//! task runs, completion-contract verdicts, token spend, guardrail
//! interventions, delivery/recovery health — delivered to every control
//! chat. Rendering is a pure function over a snapshot struct; the loop
//! only gathers, formats, delivers, and records the last-sent marker in
//! `db_meta` so cadence survives restarts. No LLM calls are involved.
